Problem: The management of Wallingford MicroBrew is considering the purchase of an automated bottling machine for $93,500. The machine would replace an old piece of equipment that costs $43,000 per year to operate. The new machine would cost $13,000 per year to operate. The old machine currently in use could be sold now for a scrap value of $5,000. The new machine would have a useful life of 11 years with no salvage value.
Required:
Compute the simple rate of return on the new automated bottling machine. Use straight-line depreciation method. (Round your percentage answer to one decimal place. Omit the "%" sign in your response.)
